Abstract
Certain thermoplastic additives that induce simultaneous low clarity and high nucleation efficacy are provided. Such additives include combinations of certain bicyclic salts (which by themselves induce very high nucleation efficacy) and certain benzylidene sorbitol acetals and derivatives (hereinafter collectively referred to as “DBSs”)(which alone provide very low haze measurements and thus highly desirable clarity characteristics). In comparison, other types of standard thermoplastic nucleators, such as sodium benzoate and sodium 2,2′-methylene-bis-(4,6-di-tert-butylphenyl)phosphate provide relatively high peak crystallization temperatures, but do not combine synergistically with DBSs to provide the same results as for the inventive combination of bicyclic salts and DBSs.
